Their Teigha "Classic" (https://www.opendesign.com/the_oda_platform/teigha_net_classic) .net platform maintains that compatibility but it feels doomed for extinction.Wrong, it's still around and not going anywhere. I built tvCAD on RealDwg. I would have a much better look at Teigha if I were to start it now.
